With this post, I shall make my attemp to create a race used in most of the games, yet unique to any.

Premise (main idea): The dwarves are technological advanced but they are very isolated from Mythoras

The history:
The dwarves are an ancient race, they were the first ones to settle them. They once lived on the grounds like everyone, sharing their lives with every other races happily. There was a nomadic race, wandering near the Dwarven Marches. The nomadic race had nothing, none of tools, nor clothing,...

The Dwarves, like they always did, happily shared their technology towards the nomadic race, they taught them the settlement, the warfare, and everything they knew. The nomadic race began to settle themselves inside the human region, their reproduction rates were higher than any race, they grew in numbers. In the matter of years, they became very aggresive and greedy. With Dwarven tools and weapons, they attacked the weaker settlements, slew many people, children, et cetera.

The dwarves were shocked when they heard the bloodshed of the nomadic race, they felt guilty, they used their tools, their technology and knowledge in order to slay others. The Mountain Emperor decided their technology is too dangerous for yet inferior but evolving races. They set up a new law, that involves the prohibition of sharing anything towards everyone, they also have to build large cities underground, in order to isolate them and let the races evolve peacefully. Dwarven armies marched towards the bloodthirsty nomadic race and slew them off, taking everything they gave them back. There are still dwarves above the ground but they are very rare, they became a legend.

Present time
An evil wizard wanted the riches from the Dwarven treasure, it's rumoured they have more gold than metal. In order to succeed this, he created alliances with the jarl Olaf Darkbeard, the jarl has influence and every dwarves knew he wanted the Mountain Emperor dead and take over. Together, they made a plan, the plan is that the wizard creating an earthquake, the dwarven underground cities will fall. The earthquakes forced the dwarves to leave the cities.

Some of the Dwarven cities, including the city of Mountain Emperor fell completly down, killing everyone in it. Only three jarls (including Olaf Darkbeard) survived the earthquake). Due the death of multiple jarls and Mountain Emperor, it caused a turmoil between the jarls.

(The player begins here)

More are to come.

Culture
The broadest sovereign of the Dwarves are the Mountain Emperor. An Mountain Emperor might appoint or confirm or tolerate subsovereigns or tributary rules styled "Jarls". The Jarls own one mountain, along with the mines inside the same mountain. But the difference between other races is that the Jarl are independent. They can do what they want, even waging war against other Jarl.

Due to the incident they caused centuries ago, they believes the dwarves are superior to any races. They are arrogant towards every races, even amongst themselves. Along with their arrogancy, their pride is very important to them. The dwarves go to any length in order to maintain their pride. They will rather choose death over defeat.

They are defensive dwarves, with a shield nearly the same size of the dwarf. The shield is very thick and heavy, they walks very slow and their stamina decreases rapidly.
When in a defensive stance, they has 200% health but they cannot move, nor fight.
Weak attack but high health. They also can use stoneform, increasing their defensive.
Weakness: horsemen

Axe throwerAn example of axethrower from BFME2
They are the best axethrowers among every races. Their axes does damage critically but they cannot throw far. They does not have many ammo but when depleted, they can fight melee.
Slightly weak but yet stronger than every laborers.
Weakness: melee

BeserkersI know, this is another race but get the general idea.
They are most agressive dwarves, they uses two mini-axes to slay them off. Their health are pretty low but they does much damage. For short time and stamina, they can turn berserk and have decreased health but increased damage.
Weakness: ranged

Prospectors
The prospectors are advanced dwarven miners. While mining, they also look for gemstones. Gemstones gives a slow tickle of gold. You have to spend crowns in order to activate the prospection.

Buildings

Tunnel
With crowns, players can spawn tunnels between mines, increasing the transport speed but they also can use for warfare.
"The best defense is attacking", using the tunnels to attack the army from their behind.

Hall of Axes
This building trains Axe Thrower, Iron Defenders and Berserkers, along with upgrades for them.

Upgrade

Prospection
Activates the gold tickle for miners when they mine the stone.

Extra

Maybe do not try to use the current dwarves, the ones you can recieve by trading with crowns. That way, you do not need to change them. They are elite among the dwarves.
